Cytolytic T cell responses increased after immunizations and cell-mediated immune (CMI) responses were induced Preliminary results revealed that activated CD4+ and CD8+ T cells were detected in a post-immunization sample exhibiting high CMI activity. While no head-to-head studies have been performed, this data compares favorably to historical controls of patients with late-stage metastatic colorectal cancer. In light of these favorable results, we are exploring a trial in late-stage colorectal cancer patients
